Great Pics!! My two roam from window to window depending on the time of day and where the sun hits.
Katie will lay in the debris you have shown in your photos just like Lenny. Tyler will do everything in his power to avoid dirt or unseemly areas. He even whines &/or whimpers when he's cleaning his feet or undercarriage after some perceived dirtiness he has been in contact with. (He'll occasionally sunbathe in, and dig in Katie's sand box, then he comes in and complains while he's cleaning the sand off!!! It's very irritating)
